You are in fact using the packages which are developed in Debian, and
just migrated to Ubuntu without much change. IMO, you should really
be using Debian rather than Ubuntu (of course, don't have to trust me,
as I am the Debian Developer in charge of this, so I am of course
vouching for the distro that I like...).

Yes, and IMO, that's really crap that they all tell "just use devstack".
I wrote about it multiple times, but it seems nobody cares much.

The problem is that everyone tests with XCP as the CentOS
appliance, and never with what is in Debian/Ubuntu. So I think
that devstack must be broken in such a case. I don't think you
will find any updated script for XCP in Ubuntu/Debian, you will
have to work it out yourself. Though I'm quite sure it shouldn't
be hard to mount your domU disk in the dom0.

Cheers,

Thomas
